### Abstract

The main of this paper is to define and investigate a new class of the degenerate poly-Frobenius-Genocchi polynomials with the help of the polyexponential functions. In this paper, we define the degenerate poly-Frobenius-Genocchi polynomials of complex variables arising from the modified polyexponential functions, and establish some explicit expressions for these polynomials. Meanwhile, some interesting connections between these polynomials and some other special polynomials are also showed.

### 4. Conclusion

Kim and Kim 7 considered the polyexponential and unipoly functions. Kim et al. 3, 11 defined and investigated the new type modified degenerate polyexponential function, the degenerate poly-Bernoulli polynomials and the degenerate poly-Genocchi polynomials. Motivated by these studying, we introduce the degenerate poly-Frobenius-Genocchi polynomials of the complex variables. We also give their some interesting properties and identities. As one of our future projects, we would like to continue to do researcher on degenerate versions of various special numbers and polynomials.
